Patent FI-963921-A (FI)
Inventor: CASCIANI JAMES R
IPC: A61B5/1464
Filed: 1996-09-30
Abstract: A pulse oximeter sensor (410) with a light source optimized for low oxygen saturation ranges and for maximizing the immunity to perturbation induced artifact. Preferably, a red (112) and an infrared light source (114) are used, with the red light source (112) having a mean wavelength between 700-790 nm. The infrared light source (114) can have a mean wavelength as in prior art devices used on patients with high saturation. The sensor of the present invention is further optimized by arranging the spacing between the light emitter (112,114) and light detectors (116) to minimize the sensitivity to perturbation induced artifact. The present invention optimizes the chosen wavelengths to achieve a closer matching of the absorption and scattering coefficient products for the red and IR light sources. This optimization gives robust readings in the presence of perturbation artifacts including force variations, tissue variations and variations in the oxygen saturation itself. <IMAGE>

Abstract: 801,835. Waveguides. COMPAGNIE GENERALE DE TELEGRAFIE SANS FIL. Jan. 14, 1957 [Jan. 26, 1956], No. 1330/57. Class 40 (8). [Also in Group XL (c)] A directive aerial installation which has an effectively high radiating position and yet in which the transducer equipment can be at ground level comprises an elevated plane reflector 3, a radiating device 7 situated below the reflector and adjacent the transducer 9, 10, and a transmission line 6 comprising a conductor having a real or artificial dielectric covering extending between the radiating device and the reflector. The angle between the reflector 3 and the vertical is chosen to direct the wave energy in the required elevational direction and a nylon cord 5 attached to the centre of the mirror supports the upper end of line 6. To produce a plane wave at the mirror end of the line 6 the dielectric coating or the artificial dielectric equivalent on the rod or tube conductor of the line must be decreased steadily from the end adjacent device 7. This may be done with an ordinary solid dielectric layer (Fig. 2, not shown), or by altering the parameters of an artificial dielectric medium. Where the artificial line is formed by spaced parallel metal annuli centred on the rod axis (Fig. 3, not shown), the diameter and/or spacing of the annuli may be varied. In the form of line shown in Fig. 4, which may be regarded as a corrugated tube or rod of constant overall diameter in which spaced grooves have been machined, the depth of the grooves is progressively reduced from the end nearest the device 7. The Specification gives the dimensions of a practical example of a line in the form shown in Fig. 4. As described, the radiating device 7 is a waveguide fed horn.

Title: Improvements in or relating to safety devices for coupled vehicles
IPC: B61H9/04
Filed: 1956-01-17
Abstract: 787,787. Positive detents for braking vehicles. KERSHAW, W. May 11, 1956 [Jan. 17, 1956], No. 1501/56. Class 103 (1). In a safety device for coupled vehicles which comes into operation on braking of a coupling to prevent the disconnected vehicle from running away down hill, a member is adapted to be connected to the vehicle and provided with means for moving it in a direction substantially parallel to the axis of the wheel so as to cause engagement of the member with an aperture in or associated with the vehicle thereby to lock the wheel against rotation and bring the vehicle to a standstill. In the embodiment illustrated applied to a pit vehicle, the safety device comprises two cylindrical sleeves 12, each secured to the chassis 10 of the vehicle so as to be opposite a pair of wheels; the axis of each sleeve 12 being parallel to and below the axis of the associated pair of wheels 11. Disposed in each open end of the sleeve 12 is a solid cylindrical rod 14 spring urged outwardly by springs 15 but held in the inoperative position illustrated in Figs. 1 and 3 by a spring-loaded releasable catch 17, pivoted 18 to the vehicle chassis, which engages the flange 16 of the rod 14. The end of the catch 17 remote from the hook end 19 is adapted to be engaged by a longitudinal cam bar 23 secured to a longitudinally movable horizontal plate 22 such that movement of the plate 22 causes release of catches 17 and engagement of rods 14 with apertures in the vehicle wheel 11 or associated member to bring the vehicle to rest. The plate 22 is provided at each end with a pivoted leg 28 such that a chain (not shown) is hooked on to one coupling 27, 28 of the vehicle and the other end of the chain is provided with a hook which may be hooked to an eye 29 provided on a horizontal plate 22 of an adjacent vehicle. Each vehicle has, in addition to the above coupling, standard couplings for attaching it to the other vehicle. On braking of a standard coupling of a train of vehicles, those vehicles which have become disconnected from the remainder and/or from the hauling means begin to become separated therefrom, the coupling 27, 28 of the last still-connected vehicle being connected with the eye 29 provided on the horizontal plate 22 of the first disconnected vehicle to pull the latter plate longitudinally operating the cam bars 23 and release the catches 17 to free rods 14 which are run outwardly to engage an aperture in the respective wheel 11 to lock the vehicle. After moving the horizontal plate 22 as described, the coupling 27, 28 of the last still-connected vehicle moves out of channel 26 which allows the pivoted lug 28 of the coupling to pivot and release itself from the chain connecting it to the vehicle from which the standard coupling is broken. The first disconnected vehicle is thus brought to a stop, which is sufficient to hold all the disconnected vehicles from further movement on the level and is sufficient to successfully bring to a stop the disconnected train of vehicles on an incline.
Patent GB-686247-A (GB)
Title: Manufacture of primary alcohols
Inventor: GASSON EDWARD JAMES
IPC: C07C29/132
Filed: 1950-01-20
Abstract: Primary alcohols are made by passing an epoxide of formula <FORM:0686247/IV (b)/1> in which R1 and R2 are alkyl, aryl or alicyclic radicals, in the vapour phase at elevated temperatures over an isomerization catalyst until substantially complete conversion to the corresponding aldehyde has taken place and subsequently conducting the mixture from the isomerization step with hydrogen over a hydrogenation catalyst at elevated temperatures. Substantially complete conversion is defined as such as results in the vapours leaving the isomerization reactor having no more than 5 per cent of the initial amount of epoxide.  Isomerization is preferably effected with inert gases, hydrogen being preferred since it may be used in the subsequent hydrogenation.  Many epoxides are specified representative being isobutene oxide and alpha-methylstyrene oxide and the oxides of propylene dimer 2,3,4-trimethyl pentene-1 and cyclohexyl-methyl-ethylene.  The reaction mixture obtained by treating alpha-di-isobutene in the liquid phase with molecular oxygen in the presence of oxidation catalysts, cf.  Specification 682,067, may also be used.  Alumina, expecially when activated, is the preferred isomerization catalyst and silica gel and phosphoric acid on carriers are also mentioned.  Isomerization temperatures mentioned are 200-350 DEG  C. and preferably the diluent gas is present in amounts to maintain the temperature at about 350 DEG  C.  Copper catalysts are preferred in the hydrogenation and temperatures specified are 180-350 DEG  C. Hydrogen, which may be used in excess, e.g. 5-10 fold, may be recycled.  In examples: (1) 1,2-epoxy-2,4,4-trimethyl pentane is passed with nitrogen over activated alumina and the pentanol obtained hydrogenated over copper on kieselguhr to the pentanol; (2) air oxidized di-isobutene is passed with hydrogen over activated alumina and the products over copper on kieselguhr to yield 2,4,4-trimethyl pentanol which is separated from methyl p  neo-pentyl carbinol and ketone which are also obtained and (3) is similar to (2) save that extra hydrogen is provided for the hydrogenation.
